Quite frankly, the people getting upset need to do one of several things--rather than the people bragging change their behavior.
1) Grow up. Realize, people playing games like to blow off excited energy through bragging.
2) Stand up. If it bugs them so damn much, they can be adults and talk to the person who is annoying them. Politely say, you know, you're being uncouth right now, and constantly bragging about how you pwned me is actually bringing me down a little. Could you lay off please?
3) Get lost. If you need to be protected by kiddie gloves, go play Club Penguin. I here the moderators there don't allow bragging either, or naughty words, or any other bad thing you can possibly be exposed to in the real world where real people are.
Quite frankly, the onus shouldn't be on the braggers. If they want to look silly for getting woodage over their +1 daggers, let them. I've come across people who bragged about stuff in a manner that bugged me in the past, I told them they were being silly and 'nuff said.
I've had people tell me it bugged me when I was "bragging"; actually two other players were mocking me but it looked like bragging to the outside party; I went and ASKED the first two players to lay off because some people were being frustrated by it.
We can all act like a bunch of adults. I don't want to play on a kiddie server.
In a kiddie server, the teachers tells all the little boys and girls to behave.
In an adult server, your friends just tell you when you're acting the fool--on BOTH sides of this issue. Without a fiat from the DM team.
Believe me, when I say, I know where this kind of misguided effort to stamp out player discourse leads. Ham-fisted attempts to reign in perceived "misbehavior" that is really no more than excited energy over the sheer awesome things that happen on this server, because some over-sensitive emo-kids are crying about it--just is a lousy precedent.
If one or two people are really so bad, that the entire DM team needed to put their full weight and authority behind a statement forbidding "nautiness" then the entire DM team would have been better served, I feel quite strongly, to talk to those two people directly. If the problem is so endemic that it affects dozens of players who are all wretchedly bragging, then the problem was probably with the emo-sissies who need to be told to grow up a little.
All in all, its just not the proper use of DM authority to step into the way a community talks. We are, for the most part, a friendly bunch of harangers. I mean, even people I HATE in IRC, I'm comfortably with when they're teasing me, bragging about whacking me, mocking me endlessly for one reason or another--because we're playing a game. Its part of gamer culture.
I think, in their effort to protect feelings, or to avoid having to deal with whining emo-sissies, or in their annoyance that people get excited when they get recognition from the DMs (like a puppy that is so happy to see you it pees on your carpet)--that the DMs issued a fiat. They forgot just how much authority anything they say carries, how much more so when it comes as an Announcement with a wide blanket statement aimed not at just the so-called "problem" players, but the entire player base that the act itself comes across as a ham-fisted effort to curb people's free speech.
The internet is not America, there is no amendment to the Constitution granting free speech--instead, the internet itself IS free speech. Such attempts will come across in a very poor light. Quite frankly, last night talking to people in IRC who felt as I do, I had to work hard to avoid the word fascist. Yet, that word sticks to mind. When people use their personal authority to curb behavior in others, that does not cause any real harm to society, you edge close to that status. With all due respect, that is what motivated my "over-reaction".
I don't apologize for that. I surely apologize for any "fascist" comments I made in private while venting. That's clearly not the case here, I know that and knew that yesterday too. However, I've not given my perspective without over-reaction, and as calmly as I can. This was, frankly I think, approached very, very poorly--but moreso, I tried to explain what I believe, based on my own experience with this same problem, is a better solution.
